invention to high chair having a pluralit of su Patented Oct. 8. 1929 CARL HESS, CF CHICAGO, ILLINOIS COLLAPSIBLE HIGH CHAIR Application filed February 14, 1927. Serial No. 167,970.

Heretofore practical folding or collapsible high chairs have not been developed, the previously known type of high chairs occupying considerablespace both in use and'in storage. Moreover, in the former devices of this character, if the tray was inadvertently left unfastened in its operative position as frequently occurred, it was a simple matter for the infant occupying the chair to elevate the tray sufliciently to allow its body to slip under and fall tothe floor, thereby resulting in injury to said infant, great mental strain to its care taker, or'both.

To obviate the above conditions this invention has been developed and relates to improvements in folding chairs and the like, and more particularly to a collapsible high chair, adapted to be folded into a compact form which occupies a small amount of space, and provided with means to automatically insure against the raising of the tray. of a high chair by the infant therein. It is an object of this invention to provide av collapsible high chair adapted to be folded into a compact form so, if desired, it may be readily-transported in a vehicle without overcrowding the occupants thereof. a

It is also an object of this invention to provide a collapsible, armless high chair, the pivoted tray of which is equipped with foolproof locking means positioned to prevent operation thereof by an infant in the chair, thereby obviating accidents to said infant. It is a further'objectof this invention to provide a collapsible armless high chair provided with a pivoted tray equipped .with pivoted supports having locking means for latching the tray in position against unlocking by an infant in the chair;

It is a further and important object of this provide a collapsible armless porting or bracing members equippe with rictional latch means'for holding the chair in locked position for use.

With these ends in finds embodiment in certain features ,of novelty in the construction, combinatiomandarrangement of parts by which the said objects and certain other objects and advantages are view, my invention,

attained, as will be apparent to one skilled in the art. 7

As shown on the drawings: a

The reference numeralxl0 indicates a collapsible high chair seat, which is supported by a set of fore legs 11, and a set of rear legs 12, said rear legs being extended to act as supports for the back 13. The fore legs 11 are inclined outwardly from the seat 10 for a purpose hereinafter described (Figure 3).

A foot rest 14 is provided between the fore legs 11 in the usual manner. A tray 15, having extended arms 15' thereon, is pivotally mounted to the rear supports 12 by the projecting pins 16 so that said tray 15 may be swung upwardly over the top of the chair back 13 to hang on the opposite side of the rear supports 12 as shown in Figure 2. Supporting members 17 are secured to the tray 15 by hinges 18 so that they may swing to occupy a position adjacent the bottom of the tray when said tray is swung back as shown in Figure 2. A male latching member 19 is secured to the lower end of each of the supporting members 17, adapted to rigidly and frictionally engage in a female member or latch socket 20 imbedded in the seat 10, said engagement being sufliciently tight to withstand the efforts of an infant to raise the tra 15. I

'I he fore legs 11 are secured to the seat 10 by hinges 21, and the seat 10 is secured to the rear supports 12 by hinges 22, thereby pronumeral 12 indicates rear legs or viding means for the said seat and fore legs to be folded simultaneously.

A pair of braces 23 and 24 are pivotally engaged on supporting pins 25 mounted on the lower portions of the rear legs or supports 12. The braces 23 and 24: are equipped at their outer ends with male latching members 19 adapted to friotionally engage in female members or latch sockets 20 imbedded in the fore legs 11.

A stop 26 is provided on each rear support 12 and the upper ends of fore legsll are cut at an angle to provide stops as shown at 27 so that when the seat 10 is lowered into its useful position it will be sufiiciently supported to enable one to secure the braces 23 and 24 into their latchedbracing positions.

Ahook or latch bar 28 is rotatably mounted on each rear support 12 and adapted to engage a projecting stud 29 mounted on each side cf the seat 10 (as shown in Figure 2) to retain the chair in its folded position.

in the modified form of this device as shown in Figures 7 and 8, the reference supports to which a tray 15 is secured by its arms 15'. Supports 17 a are secured I to the tray by hinges 18 and equipped with latching means similar to those described for the previous form of the device. A stop block 26 is secured to each of the rear supports 12 and seat 10 is secured to said block 26 by the hinges 30. A pair of fore legs 11 are secured to the seat 1O by hinges 31. Braces 23*- and as are pivotally mounted on rear supports 12 by supporting pins 25 and are provided with frictional latching means engageable with the fore legs 11 substantially as previously described. A latch bar or hook 28 is pivotally mounted on each of the rear sup- Jorts 12 adapted to engage with a projectmg stud 29 mounted on each of the fore legs P 11 adjacent to the seat the operation of the device, as disclosed n Figures 1 to 6 inclusive, assuming the chair 5 to be folded from its useful position, the tray is lifted, suflicient force being used to disengage the male latching members19 on the ends of the supports 17 from the female socket members 20 in the seat 10, and swung ever the chair back 13 to the position shown in Figure 2, the hinges 18 permitting thesu porting members 17 to assume a position a djacent to the bottom of thetray 15. The braces 23 and '24 are disengaged from the fore legs 11, the inclination of the said fore legs preventing the outer ends of the braces from falling to raised, the hinges 21 permitting the fore legs 11 to be simultaneously raised and to assume a position adjacent the bottom of the seat 10 (as shown in Figure 2-), and the latch bar 28 is engaged with the stud 29,v thereby retaining the chair in its compact form. The braces 23 and 24 are simultaneously raised by the process is reversed.

the floor. The seat 10 is then inclined fore legs 11 to their position shown in Figure 2, and the male latching members 19 on the ends of the braces 23, engage with the footrest 14 and prevent the fore legs 11 from swinging outwardly if the chair is forwardly inclined, when in its folded position, the braces 24 being supported by the inclined fore legs 11.

Obviously, is assembled for use,

when the collapsible high chair the above described When the tray 15 is swung to its useful position the supporting members 17 assume a vertical position an the male latching members 19 thereon engage with the corresponding female socket members 20 in the seat 10, thereby securing the tray in its useful position and eliminating all auxiliary sewing devices for the tray.

' In the operation of the modified form of this device, as disclosed in Figures 7 and 8, the tray, the supporting members thereon, and the latching means on the supporting mem ber's, are operated substantially as previously described. The braces 23 and'24 are disengaged from the fore legs 11*, and the chair is then lifted, the hinges and 31 permitting the seat 10 and the fore legs 11 respectively, to fall into their positions adjacent the rear supporting members 12 as shown in Figure 8, after which the latch bar or hook 28 is engaged with the stud 29, thereby securing the chair in its folded or compact form.

To assemble the chair in its useful position the latch bar 28 is disengaged from the stud 29 and the weight of the chair itself forces the seat 10 and fore legs 11' upwardly into their useful positions, after which with the fore legs 11 and the tray ad usted as previously described.

.(lbviously, if desired, the latching means the braces 23* and 24 are engaged engaging the braces 23 and 24 or 23 and 24% with the fore le s 11 or 11, may be omitted, and the said braces may be pivotally or slidably secured to said fore legs so as to fold with the said--fore legs, without departing from the principles of this invention.

From the foregoing, it is obvious, that I have provided a collapsible and folding high chair that is easily and readily folded or assembled for use, and which, when fo1d-,

ed, occupies minimum space so that when said chair is temporarily not in use, it may be folded and laid aside thereby leaving desirable space for other purposes. The invention also eliminates arms heretofore provided on high chairs and upon which the tray rested andprovides means which efie'ctively withstand any and all efiorts of an infant occupying the chair to raise the tray, thereb eliminating all danger of accidents to the said infant. Moreover, the device is simple in construction and operation, with few parts to get out of order and 1s inexpensively manufactured.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention and I, therefore, do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

Iclaim as my invention:

1. In a collapsible chair, a pair of rear supporting members, a tray, a seat, and a plurality of brace rods all pivotally secured to said rear supporting members, a pair of fore legs hinged to said seat, a foot rest secured between saidfore legs, latching members on the ends of said braces, and sockets in said fore legs removablyf receiving said latching members, said latching members being engageable with said foot rest to retain said fore legs in folded position.

2. A folding chair including a pair of rear legs, a tray, a seat, and a plurality of brace rods all pivotally secured to said rear legs, a pair of outwardly inclined fore legs hinged to said seat, and means for engaging said braces with said fore legs, said fore legs supporting said braces when dis- I engaged therefrom and elevating said brace rods when said fore legs are elevated in folding said chair, means on certain of said brace rods for retaining said fore legs in folded position.

- 3. In a device of the character described, rear legs, forelegs, a seat hingedly connected to and supported by said legs, bracing means pivoted to one set of said legs, and means on said bracing means for engagement directly with the other set of said legs to maintain said device in position for use, said last mentioned means also maintaining said other set of legs in folded position when said device is collapsed.

In testimony whereof I have hereunto subscribed my name at Chicago, Cook County, Illinois.
